This episode of BardsFM explores the legacy of Leroy Cox and the revolutionary impact of Cox Model Planes, a company that defined a golden era of American precision engineering and maker culture in the mid-20th century. The host reflects on growing up during the Gen X era, bridging analog and digital worlds, and recalls the immersive, hands-on experience of building and flying control-line model airplanes powered by Cox's legendary .049 engines—machined to aerospace-level tolerances of 25 millionths of an inch. These engines, fueled by a unique methanol-nitromethane-castor oil mix, were not just toys but precision instruments that demanded skill, patience, and craftsmanship. The episode traces Cox’s journey from a wartime electrician to a visionary entrepreneur who built a global hobby empire, only to see it decline after corporate acquisition, relocation, and the rise of digital culture. The host laments the loss of America’s manufacturing soul—where apprenticeships, human craftsmanship, and a culture of making defined innovation—arguing that today’s over-engineered, outsourced, and profit-driven models have sacrificed quality for scale. Yet, he finds hope in the resurgence of maker culture through 3D printing, vinyl records, and drone innovation, urging listeners to reclaim the spirit of individual creativity, resilience, and the joy of building something real.
Precision engineering at 25 millionths of an inch was standard for Cox engines, exceeding modern CNC capabilities.
The decline of Cox was not due to technology but to corporate dilution, outsourcing, and loss of craftsmanship culture.
Control-line flying was a form of immersive, first-person aerial combat that demanded focus, balance, and spatial awareness.
The real innovation wasn’t the engine—it was the culture of making, repairing, and learning through hands-on creation.
Today’s drone culture is a spiritual successor to Cox’s fly-by-wire era, but now constrained by bureaucracy and surveillance.

The Gen X Bridge: Analog Roots and Digital Dawn
The host reflects on growing up during the pivotal transition from analog to digital culture, recalling early computing experiences with PETs, K-Pros, and Apple computers, and the formative role of hands-on building in shaping a generation’s relationship with technology.
The Cox Engine Revolution: Precision at 25 Millionths of an Inch
“Cox engines were made to a tolerance of 25 millionths of an inch... and they had to do this because the engines were pumping out thousands a day and they couldn't afford to have anyone hand-fitting piston cylinders.”
The Culture of Making: Building, Flying, and Failing
“There was nothing else in your head while you were flying. And that's a huge statement. It was a focus issue.”
The Rise and Fall of a Maker Empire
“They tried to cheapen products leading up to that bankruptcy, which always fails. And this is a classic.”
The Death of American Craftsmanship
The episode draws a stark contrast between the mastery of Cox’s Santa Ana factory—where machinists could smell steel and feel tolerances with their fingers—and today’s outsourced, AI-driven manufacturing that lacks soul.
“Leroy Cox didn’t just build aircraft engines. He built dreams. And his visions sparked the many, many dreams of generation and generations, plural, of people that imagined what it would be like.”
“Cox engines were made to a tolerance of 25 millionths of an inch... and they had to do this because the engines were pumping out thousands a day and they couldn't afford to have anyone hand-fitting piston cylinders.”
“We have to get rid of the no and the doubt and lean into the yes, and I can.”
